OpenStreetMap Fall Editathon
Come one, come all to contribute to the Wikipedia of maps! Groups of OpenStreetMap enthusiasts from all over the country will be gathering this weekend for an #editathon.
No experience necessary. There will be an introduction for beginners at noon, and various project ideas will be provided.
Don't forget to bring your laptop and mouse (for armchair mapping or hacking), or a mobile device/pen and paper to walk around the area gathering data.
